[PATCH] D122258: [MC] Omit DWARF unwind info if compact unwind is present where eligible

[James Y Knight via Phabricator via cfe-commits]

jyknight added a comment.

> no-compact-unwind is particularly useful for newer x86_64 platforms: we don't want to omit DWARF unwind for x86_64 in general due to possible backwards compat issues, but we should make it possible for people to opt into this behavior if they are only targeting newer platforms.

Shouldn't we make `default` imply `no-compact-unwind` when the target triple OS version is high enough? (Compact-unwind was added in macOS 10.6, correct? That's lower than anyone realistically targets these days...)
